US military history is filled with units whose names not only convey a whiff of battle – 101st Airborne, 1st Air Cavalry, 14th Field Artillery – but also describe what the unit did. But what is one to make of an outfit with such a vague name as 23d Headquarters Special Troops?

Police are urging residents to keep an eye out for a black bear after one was sighted Sunday in Lincoln and again Monday morning in Weston.

The black bear was reported in the area of Routes 117 and 126 on Sunday and officials believe the animal was likely looking for food. In a message posted on Twitter, Lincoln police recommended residents take down bird feeders and remove other food sources from their yards.
